To increase your chest or go up a size, there are a couple of options. A push up bra works very. The other option which I'm not to fond about is plastic surgery but that's your decision to make.
Press ups do increase chest muscle. When you're doing then it uses your pecks and the muscle above them.
You can't increase the size of the chest for girls, it will develop naturally in its own time. The only exception would be to consider plastic surgery to increase breast size.
Why would you not want to increase your arms?
A good chest workout is to do bench presses. I think it's the best choice for working out your chest muscles. Good luck and have fun working out.
Lots of push ups can give you finely tuned chest muscles
the diaphragm and intercostal muscles increase in strength allowing for greater expansion of the chest cavity
If you click the chest it should tell ou whats avalible, you could get teleporters, production increase, medals and other stuff
The mans chest will increase by doing regular dips.
diaphagram is that major muscle
No. When you exhale, you increase the pressure in your chest cavity to push out some of the air in your lungs.
it contracts, pulling downwards to increase the volume in the chest.
The air pressure in your chest cavity increases when you are exhaling. For air to leave your lungs, it must be at a higher pressure than the air outside. Your diaphragm pushes up against your chest cavity causing the space in your lungs to get smaller. If the volume decreases, the pressure has to rise. Don't believe me? start exhaling, then close your mouth. Your cheeks will puff out because the pressure inside is greater than the pressure outside.
